摘　　要：分析了沉降控制复合桩基在竖向荷载作用下承台分担荷载作用,探讨了承台底土的强度、桩长以及作用在承台上的荷载水平和荷载作用时间对分担作用的影响,指出承台不但本身可承担荷载,且承台的效应可提高桩基承载力,考虑在沉降允许范围内减少用桩数量,亦有节约资金之潜力.This paper analyzes the function of component pile＇ s bearing platform in shearing the load under the action of the vertical load, probes into the influences of the strength of the soil on the bottom of bearing platform, the length of the pile, the load-class on the bearing platform, and the loading time on the shearing function, and points out that the bearing platform itself can not only bear the load but also increase the beaming capacity of the pile foundation with its effect, and still can save the capital considering that the amount of the pile can be reduced within bounds of settlement.

关 键 词：承台效应 荷载分担比 桩基承载力
